Option allowemptyinput true or false

Contrast this allowemptyiinput multi- head X, in which a single keyboard and mouse is associated with two or more screens under the control of one user session. Both setups will be discussed in this document as they are not mutually exclusive. I have not used the 8.0 for a while and recently needed to use it with only one monitor and it still works opiton. Now, I have an i7 20k cpu running at 4.ghz on an Asus Maxi-something computer with 12gb memory and an SSD 58gb HDD with two Asus LCD flatscreens.I am trying to install xorg on FBSD FreeBSD 9 RC3 and it is a real PITA.
